Water balance in healthy and handicapped adults

The body’s water balance is changed by food and beverage intake, metabolism, and excretion. In this study, we performed a cross-sectional study that investigated the changes of water intake and water output in healthy Japanese young and elderly people and handicapped adults. Water balance was assessed by water intake from foods and beverages, metabolic water production, non-renal water losses (NRWL), and urine volume. Most of the parameters did not change with aging in healthy adults. Estimated total water intake (ml / kg / day) increased with aging. In the healthy men, healthy women, and handicapped adults, daily water intake (median [interquartile range]) accounted for 49.4 (41.4-59.9) ml / kg, 42.9 (38.7-51.8) ml / kg, and 50.9 (43.8-74.0) ml / kg, respectively. Water loss from the kidney accounted for 19.2 (16.2-29.2) ml / kg, 22.0 (16.2-26.6) ml / kg, and 27.5 (22.7- 47.2) ml / kg, respectively. NRWL accounted for 26.6 (18.5-35.2) ml / kg, 22.4 (16.2-28.8) ml / kg, and 23.5 (19.8-28.5) ml / kg, respectively. Our findings suggest that a daily total water intake of more than 50-55 ml / kg is required to prevent dehydration in healthy and handicapped adults

Pregnant women's awareness of sensitivity to cold (hiesho) and body temperature observational study: A comparison of Japanese and Brazilian women

<p>Abstract</p> <p>Background</p> <p>Sensitivity to cold (<it>hiesho</it>) is a serious health problem in Japan, yet it is minimally understood within Western cultures. The purpose of this study was to clarify the divergence between pregnant Japanese woman living in Japan and pregnant Brazilian women living in Brazil in awareness of <it>hiesho </it>and differences between core body and peripheral temperatures.</p> <p>Methods</p> <p>The subjects of this study were 230 pregnant Japanese women living in Japan and 200 pregnant Brazilian women living in Brazil. Data was collected in June/July and November 2005 in Japan and from October 2007 to February 2008 in Brazil. The survey methods consisted of measurement of deep body temperatures and questionnaires.</p> <p>Results</p> <p>67.0% of Japanese women and 57.0% of Brazilian women were aware of <it>hiesho</it>, which showed a significant difference between the Japanese and Brazilian women (p = 0.034). The difference between forehead and sole temperatures was 2.0°C among Japanese and 2.8°C among Brazilians in June-July (p = 0.01). But in November the difference between those temperatures was 5.2°C among Japanese and 2.8°C among Brazilians (p < 0.001).</p> <p>Conclusions</p> <p>There are differences between Japanese and Brazilians both in awareness of <it>hiesho </it>and in body temperatures.</p

福祉・医療関連学科女子短大生における栄養補助食品利用の現状と問題点

The aim of this study is to clarify the present states and problems of the consumption of nutritional supplementary foods among female college students majoring welfare, medicine and health care. We investigated 406 students trough the self-reported questionnaire in April or May 2001. The subjects for analysis were 399 students.As a result, the percentages of subjects ingested balanced nutrient foods, products furnishing V.C and nutrient-containing tonics during the previous one-year were high, concerning ingestion of products furnishing iron and V.E, their percentages were low. Balanced nutrient foods were ingested for the purpose of substitute foods for snack or meal. On the other hand, nutrient–containing tonics and products furnishing V.A, V.B complex, and iron were ingested with the intention of reducing physical symptoms. The purposes of ingesting products furnishing V.A and V.C, balanced nutrient foods, and nutrient-containing tonics were significantly different between the new students and advanced students. We have concluded that strengthening of the knowledge regarding the importance of daily meal and effects of nutriments is necessary for students majoring welfare, medicine and health care
